A rotatable and concealable electrical power receptacle 1 comprises: a main body 10, a shaft section 16, an accommodating section 14, and at least one electrical outlet assembly 18. The main body 10 further includes a first housing member 101, a second housing member 103, and a pulling member 105. The shaft section 16 further includes a first shaft member 161 and a second shaft member 163. The first shaft member 161 contains an electrical power cable 26 disposed inside it. The accommodating section 14 has an interior space forming as a receiving space 12 and incorporates with the pulling member 105 to dispose an accommodating space 141 for receiving the pulling member 105. The accommodating space 141 is adjacent to the receiving space 12.

The first housing member 101 and the second housing member 103 are coupled to each other to from the main body 10. On the main body 10, there are a plurality of electrical outlet assemblies 18 are disposed on it. In the embodiment, the plurality of the electrical outlet assemblies 18 are disposed on the second housing member 103, but not limited thereto. The first shaft member 161 coupled to the main body 10 is capable of rotating transversely, so that the main body 10 and the electrical outlet assemblies 18 are substantially rotatable with respect to the central axis of the first shaft member 161 in a clockwise or a counterclockwise direction in any angle transversely. The second shaft member 163 coupled to the accommodating section 14 and the first shaft member 161 is perpendicular to the first shaft member 161, i.e. the axis of the first shaft member 161 is perpendicular to the axis of the second shaft member 163. The first shaft member 161 is capable of not only rotating transversely but also rotating with respect to the central axis of the second shaft member 163 perpendicularly. The receiving space 12 surrounded by the accommodating section 14 is able to receive the main body 10 entirely. As such, the rotatable and concealable electrical power receptacle 1 is rotatable to an exposed state in use or a concealed state when not in use by the engagement between the first shaft section 161 and the second shaft section 163, thereby increasing the flexibility of use. Furthermore, the electrical power cable 26 disposed inside the first shaft member 161 is not conflicted with the rotational movements associated with the first shaft member 161 and the second shaft member 163 in two dimensions. In other words, the electrical power cable 26 will not be knotted or damaged due to the rotational movements of the first shaft member 161 and the second shaft member 163, thereby substantially extending the service life of the rotatable and concealable electrical power receptacle 1.

An action by pulling up the rotatable and concealable electrical power receptacle 1 is by applying an external force on the pulling member 105 disposed on a periphery of the main body 10, so that the external force incorporate with the shaft section 16 forms a perpendicular force torque. The main body 10 is pulled and moved a position perpendicularly in response to the force torque. It is worth to mention that the farther the pulling member 105 is disposed away from the shaft section 16, the easier the main body 10 is rotated and moved by users. Moreover, the accommodating space 141 is designed to receive the pulling member 105 and is applicable for allowing user's hands or other tools to apply force on the pulling section 105 so as to make the main body 10 rotate.

In the preferred embodiment, schematic diagrams of the rotatable and concealable electrical power receptacle in different steps of use are shown in FIG. 2A till FIG. 2B.

As the rotatable and concealable electrical power receptacle 1 is in the concealed state, the first housing member 101 is facing upward and the second housing member 103 is actually facing downward. As such, the electrical outlet assemblies disposed on the second housing member 103 in the preferred embodiment are applicable for connecting power cables beneath the main body 10. Therefore, as per the perspective view of the first housing member 101, the connection of power cables applied with the electrical outlet assemblies 18 are not exposed outside, i.e. in the concealed mode, thereby maintaining the space of use in a tidy appearance. Moreover, because the outer surface of the first housing member 101 and the upper peripheral surface of the accommodating section 14 are aligned in the same level, the outer surface of the rotatable and the concealable electrical power receptacle 1 is adapted for users to place objects or utilize the surface without affecting working efficiency.

Next, please refer to FIG. 2B in conjunction with FIG. 2A, in which a second mode of use of the first embodiment in accordance with the rotatable and concealable electrical power receptacle is demonstrated. In the concealed state in FIG. 2A, an external force is applied on the pulling member 105 to make the main body 10 to rotate with respect to the rotational movement of the second shaft section 163 around 90 degrees, i.e. the second mode of use as shown in FIG. 28. In the mode, the main body 10 is moved and disengaged from the receiving space 1 and the electrical power cable 26 coupled to the electrical outlet assembly 18 and disposed inside the first shaft member 161 is not conflicting with the rotational movement of the first shaft member 161.

Further, please refer to FIG. 2C in conjunction with FIG. 2B, in which a third mode of use of the first embodiment in accordance with the rotatable and concealable electrical power receptacle is demonstrated. As the rotatable and concealable electrical power receptacle 1 is in the second mode, the main body 10 is capable of rotating along the axis of the first shaft member 161 around 180 degrees without restrictions in rotating directions, e.g. clockwise direction or counterclockwise direction. It is worth to mention that the electrical power cable 26 contained inside the first shaft member 161 is not knotted or damaged in response to the rotations of the first shaft member 161.

Then, please refer to FIG. 2D in conjunction with FIG. 2C, in which a fourth mode of use of the first embodiment in accordance with the rotatable and concealable electrical power receptacle is demonstrated. When the rotatable and concealable electrical power receptacle 1 is in the third mode of use, it only requires to simply apply an external force toward the accommodating section direction on the main body 10, so that a perpendicular force torque downward is generated to make the main body 10 rotate downward with respect to the second shaft member 163. Thus, under the situation, the first housing 101 is now facing downward and engages with the accommodating section 14 for making the main body 10 to be held still. And the second housing member 103 and the electrical outlet assemblies 18 disposed on it are facing outward and are exposed outside. In the fourth mode of use, i.e. the exposed state, the power cables are able to connect to the exposed electrical outlet assemblies 18 for retrieving electrical power easily. When not in use, the rotatable and concealable electrical power receptacle 1 according to the preferred embodiment can be back from the fourth mode of use, i.e. the exposed state to the first mode of use, i.e. the concealed state. First, pull the main body 10 up in 90 degrees perpendicularly, then rotate the main body horizontally around 180 degrees, and then rotate the main body 10 downward to allow it to be received completely by the receiving space 12.

In the embodiment, a power switch 20 and an indicator 22 are additionally disposed on the second housing member 103. As the power switch 20 is on and the indicator 22 emits light, it represents that the electrical power receptacle 1 is in a conduction state or functions normally; conversely, as the power switch 20 is off and the indicator 22 doesn't emit light, it represents that the electrical power receptacle 1 is in a cutoff state or functions abnormally.

Finally, please refer to FIG. 3 in conjunction with FIG. 3A, in which a diagram of a second embodiment in accordance with the rotatable and concealable electrical power receptacle according to the present invention in use is demonstrated. Further, the FIG. 3A is an exploded diagram of the A portion in FIG. 3.
